问题 I am using JavaCV in Android. In my code, I have created a ImageComparator(class of OpenCV CookBook http://code.google.com/p/javacv/source/browse/OpenCV2_Cookbook/src/opencv2_cookbook/chapter04/ImageComparator.scala?repo=examples http://code.google.com/p/javacv/wiki/OpenCV2_Cookbook_Examples_Chapter_4) Object and use that object to compare images.
